Cognition and behavior: Brain volume signals repetitive behavior

by  /  10 May 2011

Smaller-than-normal volume in several brain regions, including a region involved in relaying motor signals, could be a marker for repetitive behavior in 3-year-old children, according to a study published 7 April in Autism Research.

Cognition and behavior: Brain response to faces could signal autism

by  /  27 April 2011

At 12 months of age, infant siblings of children with autism have a brain response to unfamiliar faces that is characteristic of typical children at a younger age, according to a study published 26 March in Brain Topography. This developmental delay could be used as an early biomarker for autism.

Imaging biomarkers could signal autism spectrum disorder

by  /  12 April 2011

There does not appear to be a single genetic or environmental cause of autism, and given the heterogeneity of symptoms, coming up with a clear yes or no test for autism is challenging. Timothy Roberts argues that imaging and electrophysiology are key in the search for autism biomarkers.

Brain activity explains keen visual skills in autism, group says

by  /  4 April 2011

Individuals with autism use more brainpower in regions linked to visual perception, and less in those related to planning thoughts and actions, compared with healthy controls, according to a multi-study analysis published today in Human Brain Mapping.
